Experimental Investigation on Fly Ash Bricks using Industrial Waste

Abstract

Abstract: Although there are several benefits to using fly ash, its early lack of hydration results in low strength. In order to establish the appropriate fly ash brick mix percentage, an experimental investigation was carried out in the study. In brick specimens measuring 230mm by 110mm by 90mm, the compressive strength of various mix proportion of fly ash (14-30%), gypsum (5.5-8%), lime (14.5-30%), crusher waste (42-45%), cement (5.5%) was investigated. The objective is to find out the optimum mix design for making brick so as to achieve the maximum compressive strength.
